Did experiment suing 3 coats of RTC, Tan Kote and Resolene to find the best resist for me,with dyed leather. IMO...RTC turned out the best. Resolene 2nd and Tan Kote was last which I was later was told by one person that it wasnt a resist. Other people say it is.I was impressed with RTC. This was my first time doing any resisting. I'll continue using RTC
